How to Calculate Area of a Circle

Hi, this is Jon on behalf of Expert Village. In this video clip we'll be calculating the area of a circle. On this end table we're going to be putting a custom covering on the top and we need to figure out how much area this circle is. The first thing we need to do is find the diameter of the circle, here we have the diameter of about 16" and we're actually looking for the radius. So we're going to take 8" which is half of the diameter. What we're going to do from here is take a pie times the radius square so it'll be 3.1416 X 8 X 8 and that's going to give us a total area of 201.05 square inches of that circular top.
